Description

Technical Field

[0001] This utility model relates to the field of sports shoe manufacturing technology, specifically to a device for pressing and bonding the outsole and upper of sports shoes, and in particular a safety-type sports shoe outsole pressing device. Background Technology

[0002] In athletic shoe manufacturing, the outsole lamination process is a crucial step that determines the quality of the finished product. Existing lamination equipment generally suffers from two major drawbacks:

[0003] Safety issues: Most of the equipment uses pneumatic / hydraulic cylinders to drive the upper mold to press down, requiring operators to manually place the shoe last, which poses a very high risk of crushing hands; although some equipment is equipped with two-hand buttons or mechanical baffles, the former is inefficient and the latter cannot effectively prevent misoperation during the mold closing process, so the safety hazards have not been fundamentally resolved.

[0004] Process quality issues: The outsole of sports shoes has a complex shape, and the structure, thickness and material of the forefoot, heel, arch and other parts may be different, and their requirements for optimal pressing temperature and pressure are also different; traditional equipment uses an integrated heating plate and constant pressure output, which is difficult to cope with such differentiated process requirements, and is prone to local over-melting, under-melting or uneven pressure of glue in some areas, which seriously affects the bonding strength and product quality stability.

[0005] The existing patent number CN203467815U proposes a "safe sports shoe outsole pressing device", which only sets a safety light grid and infrared detector around the frame and lacks a specific description of the linkage control logic. The safety relies entirely on a single sensor.

[0006] Therefore, developing a pressing device that can simultaneously solve the two major challenges of operational safety and process quality is of great significance for improving the level of the sports shoe manufacturing industry. Utility Model Content

[0007] The purpose of this utility model is to provide a safe sports shoe outsole pressing device in order to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] This utility model proposes a safe sports shoe outsole pressing device, including a frame, a control system, a lower mold and an upper mold; the lower mold is disposed on the frame, and the upper mold is disposed above the lower mold, which can move up and down through a driving mechanism; the lower mold includes a lower template and a positioning mold base; it also includes a safety protection system, an intelligent pressing system and a pressure adaptive module;

[0010] The safety protection system includes a safety light curtain device and an emergency stop protection actuator. The safety light curtain device is used to monitor dangerous areas on the upper and lower paths of the module and is connected to the control system in communication. The emergency stop protection actuator is controlled by the control system.

[0011] The intelligent pressing system includes a partitioned heating module; the partitioned heating module divides the heating plate of the upper mold into at least two independent heating zones, each zone is equipped with an independent heating element and a temperature sensor, and the temperature sensor and heating element are electrically connected to the control system;

[0012] The pressure adaptive module includes miniature electric actuators evenly distributed on the pressing surface, each of which can independently fine-tune its extension stroke or output force.

[0013] As a preferred technical solution of this utility model, the safety light curtain device includes a light emitter and a light receiver, which are respectively installed on the left and right sides of the lower mold, forming one or more infrared light curtains parallel to the horizontal plane between them.

[0017] As a preferred technical solution of this utility model, it also includes a human-machine interface connected to the control system for selecting process formulas, setting parameters, and monitoring equipment status.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By using non-contact safety light curtains and a rapid-response emergency stop mechanism, an active safety protection system is constructed, which fundamentally eliminates the risk of hand crushing accidents and protects the safety of operators;

[0020] 2. Through zoned temperature control and pressure adaptive technology, "precise" pressing of complex outsoles is achieved, ensuring that the adhesive in each part reaches the optimal activation state, which greatly improves the uniformity, firmness and product yield of the bonding.

It is equipped with a 10-inch touch screen installed on the right front side of the frame as a human-machine interface.

[0026] like Figures 1 to 2 As shown, this utility model proposes a safety-type sports shoe outsole pressing device, including a frame, a control system, a lower mold, and an upper mold; the lower mold is disposed on the frame, and the upper mold is disposed above the lower mold, which can move up and down through a driving mechanism; the lower mold includes a lower template and a positioning mold base; it also includes a safety protection system, an intelligent pressing system, and a pressure adaptive module;

[0027] The safety protection system includes a safety light curtain device and an emergency stop protection actuator. The safety light curtain device is used to monitor dangerous areas on the upper and lower paths of the module and is connected to the control system in communication. The emergency stop protection actuator is controlled by the control system.

[0028] The intelligent pressing system includes a partitioned heating module; the partitioned heating module divides the heating plate of the upper mold into at least two independent heating zones, each zone is equipped with an independent heating element and a temperature sensor, and the temperature sensor and heating element are electrically connected to the control system;

[0029] The pressure adaptive module includes miniature electric actuators evenly distributed on the pressing surface, each of which can independently fine-tune its extension stroke or output force.

[0030] The safety light curtain device includes a light emitter and a light receiver, which are respectively installed on the left and right sides of the lower mold, forming one or more infrared light curtains parallel to the horizontal plane between them.

[0031] The emergency stop protection actuator is a high-speed response solenoid valve installed in the circuit of a pneumatic or hydraulic drive mechanism.

[0032] The number of heating zones is three, corresponding to the forefoot, arch, and heel of the shoe sole, respectively.

[0033] The height of the light curtain in the safety light curtain device is adjustable.

[0034] It also includes a human-machine interface, which is connected to the control system and is used for process formulation selection, parameter setting and equipment status monitoring.

[0035] Working principle:

[0036] After the equipment is powered on, the operator selects the corresponding shoe pressing formula through the human-machine interface. The PLC control system then instructs each independent heating area to heat up to the set value. The operator places the shoe last into the positioning module. At this time, the light curtain will be briefly interrupted by the operator's hands. The PLC recognizes this as a normal placement action and does not trigger an emergency stop. After pressing the start button with both hands, the cylinder drives the upper mold to move downward. Throughout the downward movement and pressing process, the safety light curtain continuously monitors the process. Once the light curtain is blocked again, the PLC immediately cuts off the cylinder power source, causing it to stop and retract, thus achieving safety protection. If the downward movement is uninterrupted, the upper mold pressing surface contacts the shoe sole. At this time, the pressure adaptive module is activated. The micro push rod array outputs force according to the preset pressure value, and the feedback is formed by the end pressure sensor to form a closed-loop control, adaptively conforming to the curved surface of the shoe sole and applying precise and differentiated pressure. After the time is up, the cylinder automatically drives the upper mold assembly to return, completing one work cycle. This achieves intelligent and adaptive pressing operation under safety protection.
